Fandoms are not exactly known for their ability to agree on everything. In fact, arguments between different fan communities are practically a genre of internet discourse in their own right. But what happens when a movie comes along that seemingly gives all of them something to agree on?
That is the premise behind the “Lesbian Space Princess Fandom War,” a TikTok trend and viral event in which users from normally unrelated fandoms jokingly declare a temporary truce to unite against the film Lesbian Space Princess. The joke is usually presented through characters from opposing fandoms extending their hands to one another, often accompanied by the phrase and meme “Just This Once.”
The trend emerged after Lesbian Space Princess became the subject of widespread online mockery in August 2026 after it was added to a major streaming service, turning the film into an unlikely common enemy for fandom communities that otherwise have little reason to cooperate.
So, how did Lesbian Space Princess trigger the “Great Fandom Truce of 2026,” and why were rival fandoms suddenly willing to make peace? Let’s find out.
Where Does The ‘Lesbian Space Princess Fandom War’ Come From?
Lesbian Space Princess is a 2025 Australian adult animated science-fiction comedy movie written and directed by Emma Hough Hobbs and Leela Varghese.
The film follows Princess Saira, an anxious and introverted lesbian from the planet Clitopolis, as she attempts to rescue her ex-girlfriend Kiki after her abduction by the Straight White Maliens.
The film received renewed attention in August 2026 after appearing in Netflix recommendations in some regions, introducing it to audiences who had not previously encountered it.
Clips, screenshots and posts about the film subsequently circulated across social media, where its exaggerated premise, character names and sexual humor made it a target for online mockery.
As criticism of the film spread, users began joking that different fandoms could temporarily set aside their usual rivalries to unite against it.
The idea developed into the so-called “Great Fandom Truce,” with users presenting fictional meetings between characters from different fandoms before declaring, “Just this once.”
The ‘Great Fandom Truce Of 2026’ Usage In Memes
The memes related to this viral trend are typically presented as a fictional alliance between two or more fandoms that would not normally be expected to cooperate.
Characters are shown extending a hand to opposing characters, often with the phrase “just this once” (or some variation) used to emphasize that the truce is temporary.
Many TikTok edits depicted characters from multiple fandoms teaming up against Lesbian Space Princess, framing the various communities as a unified force despite their normally separate interests.
The trend’s central joke comes from the idea that fandom rivalries can be temporarily forgotten when there is a sufficiently common target.
